CHARLES J. VINING, OF CLEVELAND, OHIO, ASSIGNOR TO FIELD AND HENRY J.FARWELL, BOTH OF SAME LEWIS C. MERRI- PLA CE.

ELECTRIC FIRE-ALARM AND NIGHT-CALL.

SPECIFICATION forming part of Letters Patent No. 433,584, dated August5, 1890.

Application filed December 2,

To all whom it may concern:

Be it known that I, CHARLES J. VINING, a

time, as hereinafter shown.

That the said invention may be seen and fully understood, reference willbe had to the following specification, and to the annexed drawings,making part of the same, in which- Figure 1 is a front view of theapparatus, A being the indicator, B the batteries, and C thealarm-bells. (Z d d and f are the wires of the return-current. e e e arethe wires of the induced current. Fig. 2 is an interior view of the dialD of the indicator A, which dial, with its frame, is hinged to theindicator. Fig. 3 is also an interior view of Fig. 1, show- 0 ing theclock, which is directly back of the dial D, arranged to operateconjointly therewith, and the pins and lines. Figs. 4, 5, and 6 aredetached sections of my improved apparatus.

Similar letters refer to similar partsthroughout the several views andspecification.

The center portion of the dial D of the indicator A is made of hardrubberor the equivalents thereof. In the dial is a series of conocentric circles of holes, soplaced that they will correspond with thehours and half-hours of the clock E. Around the edge of the dial isanotherseries of holes. These holes last specified are numbered so as tocorrespond With the numbers of the rooms in which the alarms C, Fig. 1,are placed. On the back of the dial D and revolving on a pivot F is anarm G, Fig. 2, to which is attached a stem H, which is engaged by thehour-hand 7c of the clock E, and causes the arm G to revolve 1889.Serial No. 332,299- (No model.)

with the hour-hand until the arm G comes in contact with one of the pinsJ, which is attached to one of the induction-wires e and placed in thehole of the dial D to correspond Withthe hour on the clock E at which itis desired to sound the alarm in the room designated. Passing throughthe dial at K and brought in contact with the arm G is thereturn-circuit wiref. Therefore when the arm G, which is continually incontact with the return-Wire f, is brought in contact with one of thepins J the circuitis closed and the alarm is sounded in the room thenumber .of which corresponds to the number of the hole in which the pinL is placed. The pin L is connected with the same wire as the pin J.This pin L representsa series, all of the series being arranged over theplate M. Every returnwire on the end next the dial has two branches, asshown in Fig. 1, and also the pins L are al- Ways in position oppositethe common switchplate M, hereinafter described. The other pin J iseither in the marginal hole numbered to correspond with the number ofthe room or At the back of the dial D is a metallic switch-plate M, ofthe shape of Fig. 6, which is attached to the dial D by means of thepivots N, turning in the insulated supports 0 and forming an insulatedpivotal switch-plate at 9, Figs. 4 and 5. Attached to the switchplate Mat the point P is a stem R, which passes through the indicator A. On theend of the stem R is a knob S, of hard rubber or any other non-conductorof electricity. It will be seen that by pulling on the knob S theswitch-plate M Will be brought in contact with all the pins in the holesin the edge of dial D, and by placing the holes so that it will come incontact withthe arm G a general and simultaneous alarm will be soundedin all the rooms having a connecting-bell.

the others the leaves or springs brought in contact with them willspring, as shown at 2', Fig. 4, and allow the remaining leaves to comein contact with their respective pins.

The alarm-bells may be of the ordinary kind with the common spools orcoils, attached to which is the ordinary armature arranged to operateconjointly with the said apparatus.

If it is desired to ring thealarm in room No. 1 at four oclock, the pinL is placed in the hole No. 1 and the pin J is placed in the hole thatcorresponds with 4:? on the clock E. The arm G, being engaged by thehourhand of the clock, will'come in contact with the pin J at the sametime that the hour-hand points to 4. The circuit .is thus closed throughthe following connections and the alarm is sounded: from battery Bthrough wire D, branch cl, through the alarm, returning through wire 6and branch y thereof to pin J, and thence through arm G and wire f tobattery.

In givinga general alarm the pin J is placed in the hole correspondingto the desired time and the knob S is pulled to bring the plate M incontact with the pins L. The bells are in multiple are, as shown, andthe course of the current for the general alarm is from the battery overthe wire D-and its branches (1 to the bells, that portion of the currentfrom the left-hand bell No. 1 going directly to the pin J over thereturn-wire e and its branch y, while the portions of the current fromthe other bells go to plate M over the several return-wires e and theirrespective branches as M. These currents unite on said plate, and thencepass through the branch 00 of the first return-wire e, and thence to thepin J, over branch y and to the battery through the arm G and wire f.

I claim as my invention- 1. In combination with a clock and an hourhandthereon, a perforated dial arranged in front thereof, an arm pivoted atthe center of said dial, a projection upon said arm with which the handengages, pins removably fitted in the perforations of said dial formaking contact with said arm, and an electrical circuit including analarm and having its terminals connected, respectively, with the pivotedarm and pins, for the purpose set forth.

2. In combination with a clock and an hourhand thereon, a perforateddial arranged in front thereof, an arm pivoted at the center of saiddial, a projection upon said arm with which the hand engages, pinsremovably fitted in the perforations of said dial for making contactwith said arm, and an electrical circuit including an alarm and havingits terminals connected, respectively, with the pivoted arm and pins, aswitch M on the said dial, and connections between said switch and themain circuit, substantially as described. In testimony whereof I affixmy signature in presence of two witnesses.

CHARLES J. VINING.
